CLEANING CONDENSER COIL

(see Figure 3
CAUTION: The drop-in refrigeration assembly condenser coil and air filter must be cleaned
every 30-days. Excessive accumulation of dust, lint, and grease on the air filter and coil will
restrict air flow through the coil and cause refrigeration assembly to overheat. Operating
refrigeration system in an overheated condition will eventually lead to refrigeration compressor
failure.
Area on top of hood must be kept free of obstructions at all times. Make sure nothing is stored on top of the
hood. Clean condenser coil and air filter as follows:
1. Place Cooling Unit power switch in " OFF"(down) position.
2. Remove top screw from ground strap securing hood to Cooling Unit.
3. Remove acorn nut securing hood on Unit, then lift hood straight up to remove.
4. Slide air filter straight up out of the condenser coil frame side rails to remove.
5. Wash out air filter with water and detergent solution, the rinse with clean water and allow to air dry.
6. Vacuum or use a soft brush to clean condenser coil. If available, use low-pressure compressed air.
7. Clean dust and dirt from around top of the refrigeration assembly.
8. Install air filter on condenser coil by reversing removal procedure.
9. Install Cooling Unit hood and secure with acorn nut.
10. Install screw in hood ground strap to secure strap to hood.
11. Place Cooling Unit power switch in " ON"(up) position.
CARBONATOR WATER PUMP MAINTENANCE (OR AFTER WATER
SYSTEM DISRUPTION)
WARNING: The carbonator water pump water inlet strainer screen and double check valve
must be inspected and serviced at least once a year under normal circumstances, and after
any disruptions (plumbing work, earthquake, etc.) to the water supply system that might
cause turbulent (erratic) flow of water through the system. A carbonator water pump with no
screen or a defective screen in the strainer would allow foreign particles to foul the double check
valve. CO gas could then back flow into the water system and create a health hazard in the water

system.
The carbonator water pump water inlet strainer screen and double liquid check valve must be inspected and
serviced at least once a year as described in WARNING note above. This procedure should be performed by a
Service Person. Refer to step 8 of " Maintenance Schedule" .
REPLENISHING CO
WARNING: CO
CO (carbon dioxide) gas leaks in the entire CO

suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO
tremors which are followed rapidly by loss of consciousness and suffocation.
